QT40-1 Semi Auto Cement Block Machine
Conveyor-fed electrical vibration press with a 30 second cycle, sized for a 60 square metre workshop and three to four workers.
Machine Overview
The QT40-1 is the first step up from hand feeding. A 6 metre belt conveyor carries the mixed batch from the JD350 pan mixer into the machine hopper, and a 13.45 kW electrical vibration press moulds the block in 30 seconds. The published layout needs about 60 square metres of covered floor and three to four workers. Moulds change the product, and the capacity table runs from 2160 pieces per 8 hours on a 400 x 250 x 200 mm block up to 17280 pieces on a 240 x 115 x 53 mm brick.
Key Benefits
- 30 second moulding cycle against 40 seconds on the hand-fed QT40-2
- Belt conveyor removes the wheelbarrow step between mixer and hopper
- 35.5 kN vibration force compacts solid brick moulds that hand presses struggle with
- 60 square metre theoretical workshop area, so it fits an existing shed
- Ships assembled: no installation work beyond connecting the power supply

Each Part And What It Does
| Item | Function | Power | Technical detail |
|---|---|---|---|
| JD350 pan mixer | Mixes sand, fly ash, cement, stone dust and aggregate | 5.5 KW | 1.2 m pan diameter |
| Belt conveyor | Carries mixed material into the machine hopper | 1.1 KW | 6000 mm long, 400 mm wide |
| QT40-1 block machine | Electrical vibration moulding; product changes with the mould | 13.45 KW | No installation required |
| Block trolley | Moves pallets to the curing area | - | 2 sets |
| Pallet | Holds blocks during curing and is reused | - | 600 pcs |
Who It Is For
- Block yards that have outgrown a manual press but not yet justified hydraulics
- Buyers with three to four workers and a 60 square metre covered area
- Projects that need several block sizes from one press
Problems It Solves
- Manual feeding that caps output no matter how fast the press cycles
- Uneven compaction on solid brick moulds where vibration force is too low
- Floor space that will not take a full automatic production line
Application Scenarios
- A block yard serving a town or district with steady daily demand
- Producing 240 x 115 x 53 mm standard bricks as a clay brick replacement
- Paving brick production at 225 x 112.5 x 60 mm for local walkway contracts
- A second shift machine alongside an automatic line during peak season
Technical Features
- 13.45 kW electrical vibration press, 30 second moulding period
- JD350 pan mixer, 5.5 kW, 1.2 m pan diameter
- 6000 x 400 mm belt conveyor rated 1.1 kW feeding the hopper
- 850 x 550 x 30 mm pallets, 600 supplied, with two block trolleys
- 3 t machine weight on a 2060 x 1730 x 1850 mm footprint
Technical Parameters
Reproduced from the manufacturer specification. Where a figure is not published the table says so rather than carrying an estimate.
| Overall size | 2060 x 1730 x 1850 mm |

| Vibration force | 35.5 KN |
| Pallet size | 850 x 550 x 30 mm |
| Pallet quantity supplied | 600 pcs |
| Machine weight | 3 T |
| Mixer model | JD350, 5.5 KW, 1.2 m pan |
| Belt conveyor | 6000 x 400 mm, 1.1 KW |
| Theoretical workshop area | 60 m2 |
| Workers required | 3-4 |
| Voltage | Built to local supply |
Quality Control In The Workshop
- Steel plate is laser cut so frame parts carry no dimensional error
- Key stress points are welded by robotic arm for a uniform weld
- Frames are shot blasted to remove surface rust before painting
- 12 month warranty on the frame, vibration system and drive motors from shipment
Use Guide
- Allow roughly 60 square metres of covered floor for the machine, mixer and conveyor
- Arrange the office, curing area and stacking area around that footprint to suit the site
- Keep three to four workers on the line: mixer, press, and pallet handling
- Rotate the 600 pallets so blocks cure fully before a pallet returns to the press
Published Output By Block Size
Capacity is indicative. Actual output varies with operator efficiency, mould and material quality, which is how the manufacturer specification states it.
| Block size (mm) | Pcs per mould | Pcs per hour | Pcs per 8 hours |
|---|---|---|---|
| 400 x 100 x 200 | 7 | 630-840 | 5040-6720 |
| 400 x 150 x 200 | 5 | 450-600 | 3600-4800 |
| 400 x 200 x 200 | 4 | 360-450 | 2880-3600 |
| 400 x 250 x 200 | 3 | 270-360 | 2160-2880 |
| 240 x 115 x 53 | 24 | 2160 | 17280 |
| 225 x 112.5 x 60 | 12 | 959 | 7679 |
How It Compares With The Alternatives
A technical comparison against the other ways of solving the same problem, using the figures each machine publishes for itself.
| QT40-2 manual machine | The QT40-2 is hand fed with a 40 second cycle and 30 kN vibration. The QT40-1 adds the conveyor, 35.5 kN and a 30 second cycle for the same three-worker crew. |
| QT4-24 semi automatic machine | Identical press specification, with a button control box added. Choose the QT4-24 when operators prefer panel control and plywood case shipping. |
| QT4-25 automatic machine | The QT4-25 moves to PLC control with automatic plate supply and brick discharge, 70-90 kN vibration and a 25 second cycle. |
